Abstract
Pulmonary renal syndrome (PRS) is a rare and life-threatening syndrome. Interstitial lung disease (ILD) has been recently considered another phenotype of lung dysfunction in patients with PRS, but there are very limited data. The characteristics of fifty PRS patients were retrospectively reviewed after a 3-year follow-up, and the differences between PRS patients whose lung dysfunction presented as diffuse alveolar hemorrhage (DAH group) and those with interstitial lung disease (ILD group) were also analyzed. The median age at diagnosis of PRS patients was 50.78 ± 17.88 years, and the main symptoms at disease onset were proteinuria (94.00%), hemoptysis (68.00%), dyspnea (32.00%) and fever (12.00%). DAH patients were younger and had significantly lower hemoglobin levels, a higher incidence of hemoptysis, and higher serum creatinine levels at onset than ILD patients. Univariate analyses of PRS patients showed that respiratory failure and the initiation of mechanical ventilation predicted patient death and that the initiation of hemodialysis and higher serum creatinine levels at onset predicted ESRD. Multivariate analyses showed that respiratory failure and anti-GBM antibody positivity could independently predict patient death. Survival analyses showed that 1- and 3-year patient survival rates and ESRD-free survival rate were not significantly different between the two groups. ILD was another important phenotype of lung dysfunction in patients with PRS. Poor outcomes were observed in PRS patients with ILD and in PRS patients with DAH.

Abstract
Anti-neutrophil cytoplasmic antibody (ANCA)-associated vasculitis (AAV) is a form of necrotizing vasculitis with few or no immune deposits. It primarily affects small and medium blood vessels. AAV is classified into three categories, granulomatosis with polyangiitis (GPA), microscopic polyangiitis (MPA) and eosinophilic granulomatosis with polyangitis (EGPA), and two major ANCAs, proteinase 3 (PR3)-ANCA or myeloperoxidase (MPO)-ANCA are involved in their pathogenesis. Intractable otitis media frequently occurs in patients with GPA, MPA or EGPA, although all patients show similar clinical features, regardless of the type of AAV. Furthermore, approximately 15% patients with otitis media caused by AAV do not show ANCA positivity, histopathological evidence, or any other AAV-related lesions at the initial visit; therefore, these patients do not fulfill the ordinary diagnostic criteria for systemic AAV. Thus, we first proposed that this condition could be categorized as "otitis media with AAV (OMAAV)". Subsequently, the Japanese Otological Society (JOS) conducted a nationwide survey between December 2013 and February 2014 and identified 297 patients with OMAAV. The survey revealed that OMAAV is a disease that initially occurs in the middle ear and subsequently spreads to other organs such as the lungs and kidneys, with eventual involvement of all body organs. Severe sequelae such as facial palsy, hypertrophic pachymeningitis, complete deafness, and subarachnoid hemorrhage resulting in death can also occur. In this review, we introduce the clinical features, diagnostic criteria, and treatment strategies recommended by JOS for early diagnosis and treatment of OMAAV.
